Гидроэнергетическая установка

Номер: RU0000183125U1

Гидроэнергетическая установка относится к гидроэнергетике и может быть использована для преобразования энергии волн или течения в реках для получения электроэнергии. Использование предлагаемого устройства позволит увеличить к.п.д. вырабатываемого электрического тока. Гидроэнергетическая установка представляет собой водяной накопительный резервуар с напорным водоводом, в котором преобразователь энергии выполнен в виде гидродинамического излучателя пластинчатого типа, а перед излучателем установлен щелевой направляющий аппарат соосно пластинчатому излучателю, причем установка снабжена несколькими дополнительными последовательными щелевыми направляющими аппаратами с гидродинамическими излучателями пластинчатого типа, расположенными по напорному водоводу. Водяной накопительный резервуар имеет сужающийся канал, являющийся концентратором потока воды, выполненный в виде двух конфузорных отражателей. Попадая на лезвие излучателя, струя жидкости срывается и образует кавитационные вихри, которые пульсируя, движутся вниз по течению водовода, схлопываются и генерируют импульсы давлений. Эти импульсы воздействуют на пьезоэлементы, расставленные вдоль водовода за защитным эластичным покрытием и за счет прямого пьезоэлектрического эффекта снимается электрический потенциал. 2 з.п., 3 ил.

Номер: US20130341937A1
Принадлежит: INTERNATIONAL BUSINESS MACHINES CORP.

Electrical power is generated from falling liquids such as captured rain water, gray water and black water in tall buildings using two or more reservoirs. Fill valves for each of the reservoirs are controlled to fill the first reservoir in a raised position while emptying the second reservoir in a lowered position. When full, the first reservoir is dropped to the lowered position while imparting mechanical energy to an electrical generator and while raising the second reservoir. Next, the second reservoir is filled until full while the first reservoir is emptied, followed by dropping the second reservoir to the lowered position while imparting mechanical energy to the electrical generator and while raising the first reservoir. The cycle is repeated so that electrical generation from the falling of the liquid avoids the liquid contacting or passing through a turbine or impeller. 1. A method for generating electrical power from falling liquids comprising:disposing a first reservoir in a system having a first raised position and a first lowered position in which movement from the raised position to the lowered position imparts mechanical energy to an electrical generator, and a bypass conduit which directs a falling liquid to pass from a height of the raised position down to a height of the lowered position;providing a first fill valve to control flow of the falling liquid into the first reservoir and a bypass valve for allowing falling liquid to pass into the bypass conduit, the open and closed states of the first fill valve and the bypass valve being under the control of a controller; and while the first fill valve is opened and the bypass valve is closed, filling the first reservoir in the first raised position;', 'responsive to the first reservoir being full, closing the first fill valve, opening the bypass valve, and allowing the first reservoir to fall to the first lowered position while imparting mechanical energy to an electrical generator;', 'responsive to the ...

A system for processing a fluid by generating water vapor through forced compression and rotation in a vessel includes capturing sea water for use in desalination processing in the vessel. Any fluid processed in the vessel, including sea water, can be used to create water vapor that rises to an elevation under its own power. After condensing the water vapor to liquid again, the condensed liquid falls upon a hydro-electric generator to generate electricity that is stored for later use. Brine output from the system can be recycled for re-processing through the system to increase water vapor yield. The wet brine output may also be dried to produce dried brine for subsequent processing of salt and other minerals. 1.

Systems store energy mechanically at a first time and extract the energy at a later time. When excess electricity from renewable sources or during off-peak periods is available, a pump directs a working liquid (L) to pressurize a gas (G) that is confined within a pressure vessel. When electricity from renewable sources is not available or during periods of peak demand or pricing, the pressurized gas (G) directs the working liquid (L) through a hydropower turbine. The turbine drives a generator through a mechanical coupling to provide electricity for powering a load. In addition, the system can leverage (take) any waste heat as the input to boost the efficiency of the system. The described systems function at ground level and are modular and scalable in capacity.
